[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The present invention provides a fire extinguisher nozzle and valve body installation structure, such as Figure 1-Figure 7As shown, it includes a fire extinguisher body 1 and an anti-corrosion layer 2; the outer side of the fire extinguisher body 1 is coated with the anti-corrosion layer 2; an inner cavity 4 is opened inside the fire extinguisher body 1, and a thickening layer 5 is integrally formed at the top of the inner cavity 4, and a mounting structure 3 is provided at the top of the fire extinguisher body 1.

[0023] In a further preferred embodiment of the present invention, Figure 1-Figure 7 As shown: the mounting structure 3 includes a valve body 301, an inner screw groove 302 and an outer thread 303. The inner screw groove 302 is opened inside the top of the fire extinguisher body 1; the valve body 301 is installed inside the inner screw groove 302, and the outer side of the bottom end of the valve body 301 is provided with an outer thread 303. The bottom end of the valve body 301 is inserted into the inner screw groove 302, and a threaded connection is formed between the valve body 301 and the inner screw groove 302. The material of the valve body 301 is brass, and the material of the anti-corrosion layer 2 is epoxy resin paint.

[0024] Specifically, in this embodiment: when manufacturing the fire extinguisher body 1, the top of the inner cavity 4 is subjected to a thickening treatment operation by the spinning machine assembly 6 to form a thickened layer 5, and the thickened layer 5 is integrated with the fire extinguisher body 1, so that the inner screw groove 302 can be opened deeper when it is opened, so that the valve body 301 is installed in the inner screw groove 302, It is more secure and not prone to falling off. After the inner screw groove 302 is opened, the bottom end of the valve body 301 is inserted into the inner screw groove 302 and rotated, thereby completing the installation of the valve body 301, making it more secure during installation.
